Compounds A and B, having the same molecular formula \( C_4H_8O \), react separately with \( CH_3MgBr \), followed by reaction with dil. HCl to form compounds X and Y respectively. Compound Y undergoes acidic dehydration in the presence of Conc. \( H_2SO_4 \) much more readily than X. Compound Y also reacts with Lucas reagent, much more readily than X, with the appearance of turbidity. Identify X and Y.
